But Jurgen Klopp has ruled out the midfielder rejoining the Welsh club this month.

Allen built his reputation at Swansea before being taken to Anfield by former boss Brendan Rodgers for a whopping £15million, but he has never cemented his place in the team in three-and-a-half years with the club.

With the Swans keen for reinforcements to help play their way out of Premier League relegation worries, it is thought Swansea made contact with Liverpool to ask about Allen’s availability and the chances of bringing the 25-year-old back home to the Liberty.

Yet it is understood the Merseyside giants have made it clear they are not interested in letting Allen leave Anfield this month as they continue to compete on four fronts having reached the knock-out stages of the Europa League and the last-four of the Capital One Cup.

Allen created a social media storm when his ‘no-look pass’ set up Jordan Ibe for the only goal in the semi-final first leg win over Stoke yet, while his performances have seemed to impress, he hasn’t been able to grab a regular spot in Klopp’s Premier League side.

And he will be keen to play his way into form ahead of this summer’s European Championships with the pass-specialist a key part of Chris Coleman’s Wales plans.

Swansea are well aware of Allen’s ability after he emerged from the youth ranks to play a pivotal role in the club’s rise to the Premier League and their first season in the top-flight under Brendan Rodgers, prompting the Northern Irishman to make a then-club record offer to take the diminutive star to Anfield with him by triggering a release clause.

Allen has less than 18 months remaining on his Liverpool contract but suggestions of talks over a new deal have cooled, with Allen recently admitting: “It’s gone very quiet. I’m not too sure really,” Allen is quoted as saying by The Guardian. “I’ve only made one league start this season, so I want to play more. I think that’s obvious for any player in that situation.

“From my point of view, it’s just about knuckling down, doing my job and giving my best, which is always what I do.”

It is not clear how much Liverpool would ask for Allen or, indeed, if they are willing to sell in the summer where Swansea will have hoped to have retained their elite status and look to rebuild a side.

Swansea have limited funds to spend this window – with the club willing to consider cashing-in on some players to free up finances – and the priority spend will be on a striker. Swansea have already banked £12m from the sale of former Liverpool midfielder Jonjo Shelvey to Newcastle with Jonathan de Guzman a possible loan replacement while another old boy in Scott Sinclair has also been targeted for a cut-price return to the Liberty.
